Expression of (A) CXCL1, (B) CXCL5 and (C) CXCL6 in different tumor categories of colorectal carcinoma (CRC) as determined by Q-RT-PCR. Q-RT-PCR data are expressed as mean +/- standard error of the mean (SEM), * P < 0.05, ** P < 0.001, n = 23 and 25, respectively. Fold increase above 1 indicates chemokine overexpression in CRC tissues related to unaffected neighbor tissues, respectively. Note the different scale for CXCL1, CXCL5 and CXCL6 expression.
